SPECIFICATION forming part of Letters Patent No. 580,857, dated April20, 1897.

Application tiled June 6, 1896. Serial No. 594,589. (No model.)

To @ZZ whom it may concern:

Be it known that I, ENOCH R. GARRETT, a citizen of the United States,residing at Appleton City, in the county of St. Clair and State ofMissouri, have invented a new and useful Steamer, of which the followingis a specification.

The invention relates to improvements in Steamers.

The object of the present invention is to improve the construction ofthe steamer shown and described in Patent No. 545,7 90, granted meSeptember 3, 1895, and to increase the durability and efficiency of thesame and to enable feed to be steamed while the latter is in amixing-trough, and also to enable hot water or steam to be rapidlyfurnished for bath-rooms, laundries, fruit-evaporators, and the like.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective view of a steamerconstructedv in accordance with this invention. Fig. 2 is a verticalsectional view of the same. Fig. 3 is a detail perspective view of thedetachable iire-boX or furnace. Fig. 4 is a detail sectional viewillustrating the manner of mounting the door for supplying fuel to thefire-box or furnace. Fig. 5 is an enlarged detail sectional viewillustrating the construction of the inwardlyopening valve.

Like numerals of reference designate correspending parts in all thefigures of the drawings.

The body of the steamer comprises two separate and independent annularchambers l and 2, and the chamber 1 is composed of a taperingcylindrical inner wall or sheet 3, decreasing in diameter toward thetop, and an outer tapering wall or sheet 4, arranged concentric with theinner sheet or wall 3 and tapering slightly less than the latter to makethe intervening space between them slightly wider at the top than at thebottom. The inner and outer walls 3 and 4 are connected at their upperand lower edges by annular top and bottom plates 5 and 5a.

The chamber 2 has an inner cylindrical sheet or wall 6, which slightlytapers from its top to its bottom and rests upon the cap-plate 5, andthe said chamber 2 also has an outer tapering cylindrical wall or sheet7, which surrounds the inner wall 6 and extends down over and surroundsthe inner chamber l, ter- 1 minating at a point just above the bottom ofthe said inner chamber and being united thereto, as shown at 8. Thediameter of the outer wall or sheet 7 increases as it approaches thetop,where it is connected by an annular plate or cap 9 with the upperend of the inner wall or sheet 6. Two separate and independentwater-containin g chambers are thus provided, One overlapping the other,and the intermediate wall 4 between said chambers is provided with upperand lower apertures 10 and 11 for the circulation of water and steam.

A vertically-disposed smoke iiue or pipe 12 is employed, and it has itslower end resting upon the inner edge of the cap-plate 5 of the lowerchamber.

The furnace or iire-boX,which is constructed substantially the same asthat shown in the above-mentioned patent, consists of a cylindrical box15, which is provided at one side with a perforation 16 and at theopposite side with a notch or open slot 17, said perforation and notchbeing adapted to receive the shaft on which a du mping-grate 18 issupported. Suitable rotary projecting brackets 19 are attached to theexterior surface of the fire-box at suitable intervals, the upper edgesof such brackets being in the same horizontal plane with the upper sideof the weightsupporting shaft and adapted to receive the lower edge ofthe steamer. The grate-supporting shaft is thus held in place when thefire-box is in use, but may be removed when the latter is detached fromthe steamer. A series of pivoted loops, connected to the lower end ofthe chamber l upon the exterior wall thereof, pass beneath and engagethe brackets 19 on the fire-box, thus coupling the parts together. Ahinged door 2O at one side of the fire-box is provided for the removalof the ashes and affords the necessary draft.

The lower chamber 1 is provided with a door-opening communicating withthe space inclosed by the inner wall 3, and it has a hinged door 14, bymeans of which fuel is supplied to the fire-box or furnace. The innerIOO and outer walls 3 and 4 of the lower chamber are provided withsuitable flanges for closing the interveningsp'ace between them aroundthe door-opening.

In the operation water is introduced into the chambers l and 2 through asupply-pipe or filling-tube 2l, arranged within the upper chamber2,adjacent to the outer wall 7 thereof and extending downward from the topplate 9 to the point of juncture between the walls 7 and 4 andcommunicating with the lower chamber l. The filling-tube or supply-pipeis provided at its top with a suitable funnel, and sufficient water isintroduced into the steamer to fill the latter substantially to theupper end of a water-gage 22, mounted on the exterior of the wall 7 ofthe upper chamber and provided with a glass tube mounted in a suitableframe. Another faucet 23, located at the bottom of the inner chamber l,provides for drawing o the water when desired. A fire having beenkindled in the furnace-box 15 the products of combustion pass up withinthe space in the inner wall of the lower chamber l, and thence outthrough the smoke iiue or pipe l2. In their passage they heat the waterin the chamber l to a boilingpoint, when it passes out through the upperaperture l0 in the outer chamber 2, the cold water therein passingdownward and through the lower aperture 11 into the inner chamber. Thesteam finally escapes into the upper end of the upper chamber and isconveyed through a iexible hose or pipe 24 to the desired point. Thesteam pipe or hose is provided at its end with a metallic sleeve 25,which receives a detachable steam register or distributer 26, made ofperforated sheet metal and adapted to -be inserted into the feed.

The upper chamber is provided at its top or cap plate with aninwardly-opening valve 27, adapted, when the upper chamber is filledwith steam and water, to be closed automatically by the steam, andcapable, when the steam is exhausted, to open automatically and admitair into the upper chamber to prevent the steamer from collapsing underthe atmospheric pressure when it is not supported by sufficient interiorpressure. It ofttimes happens that the steamer is employed for heatingfeed and that the nozzle is left in the feed, which practically closesthe same, so that air cannot enter it. Should the fire be permitted togo out when the nozz'le is inthe feed, the .steam would exhaust in theupper chamber, as, the lower end of the filling-tube being submerged inthe water contained within the -upper chamber, no air could possiblyenter, and if the inwardly-opening valve were not provided the steamermight collapse under the atmospheric pressure. The inwardlyopeningvalve, which may be constructed in any suitable manner, preferablyconsists of a perforation, a valve-stem, and a valve-plug, together withsuitable means for supporting the valve-plug and steam when the valve isopen.

The steamer, which is provided at opposite sides with rigid handles 28,is removablyT mounted in a supporting-frame 29, comprising taperingcorner-posts 30 and upper and lower connecting-bars 31 and 32. Thesupporting-frame is open at its top to receive the steamer, and thelatter has its handles 28 resting upon the adjacent top bars 31.

It will be seen that the durability and efficiency of the steamer areincreased, as the illing-tube or supply-pipe is arranged on the interiorinstead of on the exterior and a valve is employed to prevent thesteamer from collapsin g when the steam is exhausted from the upperchamber, and that an increased amount of water is arranged at the lowerextremity of the lower chamber to prevent any liability of the partsbeing burned out at that point.

Changes in the form,.proportion, and minor details of construction maybe resorted to without departing from the principle or sacrificing anyof the advantages of -this invention.

What I claim isl. In a steamer, the combination of a lower or innerchamber comprising inner and outer tapering walls forming an interveningspace slightly greater in width at its top than at its bottom, and topand bottom plates connecting the upper and lower edges of the inner andouter walls, an upper chamber surrounding the upper portion of the inneror lower chamber and composed of inner and outer cylindrical walls and atop plate connecting the upper edges of the same, an inwardlyopeningvalve arranged atthe top of the upper chamber, an interiorly-arrangedfillingtube extending from the top of the upper chamber to the bottomthereof and communicating with the inner or lower chamber, and aflexible hose extending from the upper chamber, substantially asdescribed.

2. In a steamer, the combination of the tapering annular inner or lowerchamber, composed of inner and outer walls and provided with adoor-opening communicating with the space inclosed by the inner wall, adoor hinged to the lower or inner chamber, the upper cylindrical chambermounted on and surrounding the upper portion of the lower or innerchamber and composed of inner and outer cylindrical walls, a smoke-pipearranged within the inner wall of the upper chamber, and a fire-box orfurnacearranged at the bottom of the inner or lower chamber,substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
